Research on energy saving algorithm of datacenter in cloud computing system
云计算系统中数据中心的节能算法研究

This paper briefly described the definition and characteristics of cloud computing, and focused the high energy consumption problem of cloud datacenter. Based on the classification of the energy saving algorithm, it researched the three kind of energy saving algorithms in a big way, including the energy saving algorithm based-DVFS, energy saving algorithm based-virtualization and the energy saving algorithm based-turn off/on of hosts, and made a comparative analysis of the advantages, disadvantages and applicable scene of these algorithms. Finally, it sumed up the further research problems for energy consumption management in cloud computing datacenter.
